The grapevine (Vitis vinifera) is one of the oldest cultural plants whose living ancestor still exists. The aim of this study was to determine the types of wines and their classification according to categories of quality. From the many types of grapes for wineproduction the most important genus is Vitis, which is divided into two subgenera: Muscadine and Euvitis.
There are various types of wines that reflect the diversity of climate and soil on which different types of vines are grown. We usually differ wines by color: white, rose (pink) and black (red) wine - and the color determines the color of grape berries with wine production process. Wines are classified into categories depending on the quality of processed grape,
yield per hectare, the mellowwnes of the grapes, treatment and care, content of natural alcohol and other constituents and organoleptic (sensory) properties. By law, the Croatian wines are divided into: wine in the narrow sense of the word (still wines, sparkling wines, semi-sparkling wines, sparkling wines) and special wines (dessert wines, flavored wines,
liqueur wines). By analysing the parameters which determine the quality of wines they are classified into wines, quality wines and premium wines.
